OpenCode is an open-source AI coding agent designed for developers who want to use AI directly inside their terminal, IDE, or desktop workflow.
It helps developers understand codebases, plan changes, write code, run tasks, and work with multiple AI models without being locked into a single provider. OpenCode can connect to popular model providers such as Claude, GPT, Gemini, and local models, making it flexible for different coding styles, budgets, and privacy requirements.
One of its strongest advantages is that it is terminal-native and developer-focused. It supports multi-session workflows, LSP-aware context, shareable sessions, and different working modes such as planning before making code changes. This makes it useful for developers who want more control over how an AI agent interacts with their projects.
Because OpenCode is open-source and MIT licensed, developers can inspect the code, contribute to the project, customize it, and use it as an alternative to closed AI coding tools. It is especially attractive for users who like tools such as Claude Code, Cursor, GitHub Copilot, or other agentic coding environments, but want a more transparent and provider-agnostic option.
Overall, OpenCode is a powerful open-source AI coding agent for developers who want speed, flexibility, model choice, and more control over their AI-assisted development workflow.

Agents
OpenCode includes two built-in agents you can switch between with the Tab key.
- build - Default, full-access agent for development work
- plan - Read-only agent for analysis and code exploration
- Denies file edits by default
- Asks permission before running bash commands
- Ideal for exploring unfamiliar codebases or planning changes
Also included is a general subagent for complex searches and multistep tasks.
This is used internally and can be invoked using @general in messages.
